Let us make ourselves present in this divine work. Let us take a drop from the sea; in it we shall be able to espy the very process of the primitive creation. Nature's God is ever consistent; he does not work in one fashion to-day, and in another to-morrow. This drop of water, I doubt not, will tell us in its transformations, the tale of the Universe. Let us be patient, and observe. Who can foresee or guess the history of this drop of water? Which will it first produce, the vegetable-animal, or the animal-vegetable? Will this drop be the infusoriæ, the primitive _monad_, which, vibrating, shall shortly become _vibrion_, and ascending step by step, from rank to rank, polypus, coral, or pearl, may perchance in ten thousand years reach the dignity of insect? Will it produce the vegetable thread, so slight and silken that one would scarcely discern it, and yet already is no less than the first born hair, amorous and sensitive, which is so well known as _Venus's hair_? This is no fable--it is true natural history. This hair, of double nature, at once animal and vegetable, is, in fact, the commencement of life. Look quite down into the depths of a vessel of water; at first you discover nothing; patience for a few moments and you perceive drops, atomies, that are moving. Bring a good glass into the service, and you see a whole cloud of these atomies. Are they gelatinous or fleecy? Under the microscope this seeming fleece becomes a group of filaments, of finest and silkiest threads; a thousand times finer, it is believed, than the finest hair that adorns the head of woman. You are now looking upon the first timid attempt of life that is struggling to achieve organization. These confervæ, these hair-weeds, are to be found wherever there is stagnant water, whether fresh or salt. They are the commencement of that double series of the primary vegetation of the sea which became terrestrial when the earth emerged from the watery depths. Once above and beyond the waters, they become the vast, the numberless Fungus-family; in the water, they are the hair-weeds, the many-formed and many-named Algæ.
